- Find the point on the line y = 3x + 2 that is closest to the origin.distance to the origin squared: d 2 =(x-0) 2 +(y-0) 2 = x 2 +(3x+2) 2 =x 2 +9x 2 +12x+4 = 10x 2 +12x+4. Take the derivative, set to zero and solve for x
- Use Lagrange multipliers to find the point (a,b) on the graph of y=e^3x ...We want to find the min. values of the product f(a,b)=ab subject to the constraint y=e 3x. For simplicity let's use f(x,y)=xy. Using Lagrange multipliers, we want to solve ∇f=λ∇g and g(x,y)=0. First, we know g(x,y)=0 if x=0 and y=1. We find that f(0,1)=0. ∇f=λ∇g and g(x,y)=0 can be written as . f x =λg x. f y =λg y g(x,y)=0. This gives
- If f(x) = x2 + 3x + 1, what is f(x + 2)? Please step by step ... - WyzantHi Maria, all you need to do is replace x with x + 2 where ever x occurs in the original function. Given function:
- Solving systems of equations | Wyzant Ask An Expert3x +0y = -15 3x = -15 3 3 x = -5. step 2: now you know the value of x, you can plug it back into one of the equations and solve for y! The second equation is the best since there are no coefficients of x or y. x - y = 2-5 - y = 2 +5 +5-y = 7 y = -7. Step 3: plug x and y into eqations to check your answers! 2x + y = -17 2(-5) + (-7) = -17
